This application is a continuation-in-part of U.S. application Ser. No.11/634,714, filed Dec. 6, 2006, which is hereby incorporated byreference in its entirety.

FIELD OF THE INVENTION

This invention relates to the collecting and measuring of body fluid.More specifically, the present invention is directed to a sanitary fluidcollection system and methods of using such a system.

BACKGROUND OF THE INVENTION

Fluid collection systems are typically used in hospitals to monitor thedischarge of urine, blood, or exudate from bedridden patients. Suchfluid collection systems include a fluid collection bag. The catheter istypically connected to the fluid collection bag and is generallysuspended at a patient's bedside. Fluid collection bags generally havean inlet tube near the uppermost portion of the bag where the urineenters and an outlet near the bottom portion of the fluid collectionbag, which permits discharge of the urine.

Medical beds that raise and lower are commonly used in healthcarefacilities. Placing medical beds in a low position is recommended forpatient safety. Having medical beds in a low position makes it easier totend to patients and provides for a shorter fall should a patient fallfrom the bed. However, many fluid collection bags rest on the floor whenmedical beds are in their low position. Since the outlet is typicallylocated at the bottom portion of fluid collection bags, there exists thepotential for contamination and the spread of bacteria when fluidcollection bags are permitted to rest on the floor.

Accordingly, there exists a need to provide a fluid collection systemhaving a fluid collection bag that is adapted to suspend from a medicalbed in a low position without contacting the floor. It would, thus, bedesirable to have a fluid collection system having a fluid collectionbag that addresses this need.

DESCRIPTION OF ILLUSTRATIVE EMBODIMENTS

The phrases “fluid collection bag” and “fluid collection system” areused throughout the description and will, thus, be defined for claritypurposes. A “fluid collection bag” is a receptacle for collecting bodilyfluid, such as urine, blood, and exudate. A “fluid collection system”includes a receptacle, tubing, connectors, and mechanical supports andmay include a means to prevent the backflow of fluid.

Referring initially to FIG. 1, a fluid collection bag 10 adapted for usein a fluid collection system 70 (shown in FIG. 3) is illustrated. Thefluid collection bag 10 is generally comprised of plastic. However, thefluid collection bag 10 may be comprised of any impervious flexible,rigid or semi-rigid material. The fluid collection bag 10 has a firstside 12 and a second side 14 along a length L of the fluid collectionbag 10. The fluid collection bag 10 further includes a first end 16 anda second end 18 along a height H of the fluid collection bag 10. Thelength L of the fluid collection bag 10 is generally greater than theheight H of the fluid collection bag 10. In other words, the fluidcollection bag 10 has a longitudinal axis LA (illustrated in FIG. 3)aligned with the length L of the fluid collection bag 10. In oneembodiment, the length L of the fluid collection bag 10 is approximatelytwice as long as the height H of the fluid collection bag 10. In otherembodiments, the fluid collection bag 10 may have a length L rangingfrom about 1.5 to about 5 times the height H of the fluid collection bag10. However, other dimensional proportions are contemplated and may beused in accordance with one or more embodiments of the presentinvention. Despite the potential variation in length and heightproportions, an elongated length and a shorter height assist in enablingthe fluid collection bag 10 to hang on a bed frame and not contact theground when the bed is in a low position. Thus, the elongated length andshorter height assist in inhibiting the potential for contaminationand/or spread of infection. While the fluid collection bag 10 is shownhaving a generally rectangular shape, the fluid collection bag 10 maytake other polygonal and non-polygonal forms.

The first side 12 includes a side reinforcement 20 having one or moreside openings 22. The side reinforcement 20 and side openings 22 areadapted to enable the fluid collection bag 10 to be attached to amounting bracket 50 (see FIG. 2) or other mounting device, as will bedescribed below. Although three side openings 22 are depicted in theembodiment of FIG. 1, any number of side openings 22 suitable forassisting in mounting or otherwise affixing the fluid collection bag 10onto a mounting bracket 50 or other mounting device may be used. Theside reinforcement 20 is generally comprised of plastic. However, othermaterials may be used for the side reinforcement 20, such as woven ornon-woven material, molded or stamped material, wood, metal, paperboard,or any rigid or flexible material. The side openings 22 may be generallyelliptically-shaped and should be of a size sufficient to facilitateaffixing, mounting, hanging or manipulating the fluid collection bag 10.The side openings 22 may take other shapes than those depicted in theFIGS. The side openings 22 are generally reinforced for ease of use anddurability.

The first end 16 and the second end 18 include end reinforcements 24having one or more end openings 26. The end openings 26 assist inenabling the fluid collection bag 10 to be handled by a nurse or otherhandler of the fluid collection bag 10. Additionally, the end openings26 assist in permitting the fluid collection bag 10 to become associatedwith and/or affixed to other types of objects (see, e.g., FIG. 4). Byproviding one or more side openings 22 and one or more end openings 26at different locations on the fluid collection bag 10, the fluidcollection bag 10 may be secured to various types of objects including,but not limited to, a bed such as a medical bed, patient aids such as apole, a chair, a wheelchair, a walker, and a person. The endreinforcements 24 are generally comprised of plastic but can becomprised of woven or non-woven material, molded or stamped material,wood, metal, paperboard, or any rigid or flexible material, as well. Theend openings 26 may be generally elliptically-shaped, but may also takeother shapes. Furthermore, the end openings 26 are of a size sufficientto facilitate affixing, mounting, hanging or manipulating the fluidcollection bag 10. The end openings 26 are generally reinforced for easeof use and durability. Although a total of six end openings 26 aredepicted in the embodiment of FIG. 1, any number of end openings 26suitable for assisting in affixing, mounting, hanging or manipulatingthe fluid collection bag 10 onto an object may be used. It should benoted that the side openings 22 on the side reinforcements 20 and theend openings 26 on the end reinforcements 24 are generally symmetrical,thereby enabling the fluid collection bag 10 to be affixed, mounted,hung or manipulated to any side of a bed or other object.

An inlet opening 27, adapted to receive an inlet tube 28, and an outletopening 29 having an outlet tube 30, are located along the first side 12of the fluid collection bag 10. However, it is contemplated that thefluid collection bag 10 may have additional inlet and outlet openingsand tubes. Additionally, the inlet and outlet openings 27, 29 may belocated in other positions on the fluid collection bag 10 than thoseillustrated in the FIGS. Before use of the fluid collection bag 10, theinlet tube 28 is associated with the fluid collection bag 10 at theinlet opening 27 at one end. The exposed end of the inlet tube 28 istypically connected to a catheter (not illustrated). The outlet tube 30is associated with the fluid collection bag 10 at the outlet opening 29at one end. The exposed end of the outlet tube 30 may be inserted into adrain tube holder 31.

In the illustrated embodiment, the inlet tube 28 associates with thefluid collection bag 10 at an angle to reduce twisting and to allow forgood drainage. In one embodiment, the inlet tube 28 may associate withthe fluid collection bag 10 at an angle within the range of about 30° toabout 50°. However, it is contemplated that any angle which is suitablefor reducing twisting and allowing good drainage for the inlet tube 28may be used.

Near the inlet opening 27 and internal to the fluid collection bag 10 isan anti-reflux mechanism 32. The anti-reflux mechanism 32 is adapted togenerally surround the inlet tube 28 and comprises two sheets 32 a, 32 bhaving different lengths in the embodiment shown in FIG. 1. Theanti-reflux mechanism 32 may be comprised of vinyl; however, othermaterials are contemplated for use. Some non-limiting examples ofmaterials for use in the anti-reflux mechanism 32 include plastic film,molded plastic, and rubber. At one end, at least one sheet, i.e., 32 aor 32 b, of the anti-reflux mechanism 32 may be associated with thefluid collection bag 10 at or near the inlet opening 27 or the inlettube 28 itself. The other end of the anti-reflux mechanism 32 is free.The anti-reflux mechanism 32 assists in allowing fluid to enter thefluid collection bag 10 while inhibiting fluid from exiting the fluidcollection bag 10 through the inlet tube 28. To inhibit fluid fromexiting through the inlet tube 28, the sheets 32 a, 32 b collapse andassist in sealing the end of the inlet tube 28 internal to the fluidcollection bag 10 when fluid attempts to exit through the inlet tube 28.It should be noted that other types of anti-reflux mechanisms havingdifferent designs and/or different numbers of sheets may also be used.

A user may control the exit of fluid from the fluid collection bag 10through the outlet tube 30 using a valve 34. The valve 34 may be any ofthose types of valves adapted to open or close a fluid path to allowfluid to drain or keep fluid from draining. In one embodiment, the valve34 is adapted to replace a drainage hole with a post when activated. Inother embodiments, the valve 34 may, for example, be a twist valve, atube that closes with a mechanical compression against it, or a rollerclamp. Additionally, in some embodiments, more than one valve may beutilized.

The inlet tube 28 and the outlet tube 30 may include one or more ribs 36to discourage kinking or compression within the inlet and outlet tubes28, 30. The ribs 36 enable good flow through the inlet and outlet tubes28, 30 and allow for good drainage of the fluid collection bag 10. Thefluid collection bag 10 may also include a vent 39 and a printed window38. The vent 39 is a hydrophilic air vent allowing air transfer toinhibit pressure effects such as a vacuum effect in the fluid collectionbag 10. The printed window 38 has measurement line(s) to enable easyurine volume output determination.

Referring now to FIG. 2, the mounting bracket 50 is illustratedaccording to one embodiment of the present concepts. The mountingbracket 50 is generally comprised of a rigid material for stability.Some non-limiting materials that may be used for the mounting bracket 50include plastic, wood, metal, or paper board. The mounting bracket 50may include a base 52 and optionally one or more support members 54. Thebase 52 has a first end 60 and a second end 61 along a base width W₁ ofthe mounting bracket 50. The base 52 further includes a first side 65and a second side 63 along a base length L₁ of the mounting bracket 50.The base width W₁ may be about one-half of an inch (about 1.27centimeters) or more. In one embodiment, the base width W₁ is about sixinches (about 15.24 centimeters). In one embodiment, the base length L₁is about ten inches (about 25.4 centimeters). However, other sizes arealso contemplated and the base length L₁ may be any length sufficient tosupport the fluid collection bag 10. The support member 54 extends fromthe base 52 at about the first side 65 of the base 52 in a generallyperpendicular direction opposite to attachment members 62. While themounting bracket 50 is depicted in FIG. 2 as having a generallyrectangular shape, it is contemplated that other shapes may be used. Itis contemplated that the mounting bracket 50 may take on anyconfiguration or size that is suitable for mounting or otherwiseaffixing the fluid collection bag 10 onto a bed frame or other desiredobject.

Generally, the mounting bracket 50 is adapted to removeably associatewith an object, such as a bed for example. More specifically, the base52 and the support member 54 of the mounting bracket 50 are adapted tocontact an end of a bed frame, wherein the base 52 rests on top of thebed frame and the support member 54 may contact the side of the bedframe (see, e.g., FIG. 3). Although a generally rectangular shape isshown, the shape of the base 52 and support member 54 may vary to enablea removeable attachment to different types of objects and differentdesired end uses. Furthermore, the mounting bracket 50 may includecomponents other than or in addition to the base 52 and support member54 to associate with desired objects. To enhance the attachment of themounting bracket 50 to certain objects, the base 52 may include one ormore securement tabs 58 located along the first end 60 and/or the secondend 61 of the base 52. The securement tabs 58 will be described infurther detail below.

As mentioned above, the fluid collection bag 10 is adapted to associatewith a mounting bracket such as the mounting bracket 50 depicted in FIG.2 or with any other mounting device. The mounting bracket 50 may includeone or more attachment members 62 adapted to associate with the one ormore side openings 22 of the fluid collection bag 10. Although themounting bracket 50 is shown with two attachment members in FIG. 2, anynumber of attachment member(s) suitable for mounting or otherwiseaffixing the mounting bracket 50 or other mounting device to the fluidcollection bag 10 may be used. The attachment members 62 form an angle αwith the base 52 of the mounting bracket 50. In some embodiments, suchas that shown in FIG. 2, the angle α is about ninety-degrees (about90°). In other embodiments, the angle α may be greater than 90° (i.e.,an obtuse angle). Having an angle α greater than 90° allows the fluidcollection bag 10 to hang away from the bed and allow room for fluid toexpand the fluid collection bag 10. In some embodiments, the angle α isbetween about 90° and about 110°.

The attachment members 62 may include a top portion 67 having an inlettube guide 64. The inlet tube guide 64 on the top portion 67 is adaptedto receive and hold the inlet tube 28 in place when the fluid collectionbag 10 is associated with the mounting bracket 50. The top portion 67 isangled and assists in providing good placement of the inlet tube 28 forgood drainage. In the embodiment depicted in FIG. 2, the inlet tubeguide 64 is provided on both attachment members 62 because the mountingbracket 50 is “reversible” and may be used on either side of a bed orobject. However, in other embodiments, only one of the attachmentmembers 62 may include an inlet tube guide 64. The mounting bracket 50may optionally include one or more center attachment members 66 toprovide additional support for the fluid collection bag 10. The centerattachment member 66 may be adapted to associate with one or more sideopenings 22 of the fluid collection bag 10.

In some embodiments, the mounting bracket 50 may include one or morecut-out portions 69 adapted to receive the inlet opening 27 and inlettube 28 of the fluid collection bag 10 to facilitate flush mounting ofthe fluid collection bag 10. The mounting bracket 50 is not limited tocomprising one continuous piece. To facilitate storage, shipping, andhandling of the mounting bracket 50, the mounting bracket 50 maycomprise a plurality of pieces adapted for assembly.

Referring now to FIG. 3, the fluid collection system 70, including thefluid collection bag 10 and the mounting bracket 50, are illustrated inuse. The base 52 and support member 54 (not visible) of the mountingbracket 50 contact a bed frame 71. The side openings 22 of the fluidcollection bag 10 have been placed over the attachment members 62 andcenter attachment member 66 to provide a removeable attachment betweenthe fluid collection bag 10 and the mounting bracket 50. The securementtabs 58 have been bent by a user around portions of the bed frame 71 tofurther secure the mounting bracket 50 to the bed frame 71. The inlettube guide 64 maintains the inlet tube 28 in an optimal position forfluid flow through the inlet tube 28.

As illustrated, the longitudinal axis LA of the fluid collection bag 10is oriented substantially parallel to the ground. Having the outlet tube30 associated with the fluid collection bag 10 at or near the first side12 of the fluid collection bag 10 keeps the outlet tube 30 away from theground. By having the outlet tube 30 associated with the fluidcollection bag 10 at or near the first side 12 of the fluid collectionbag 10 and by keeping the collection bag 10 away from the ground, therisk for contamination and/or spread of infection when a bed is in a lowposition is reduced.

As mentioned above, the end openings 26 on the end reinforcements 24 areprovided to enable attachment of the fluid collection bag 10 to objectsin addition to beds. Such additional objects include, but are notlimited to, patient aids such as a pole, a chair, a wheelchair, awalker, and person. Referring now to FIG. 4, the fluid collection bag 10is shown associated with a wheelchair 72. As shown in FIG. 4, one ormore pieces of securement material tape 74 may be used instead of or inaddition to the mounting bracket 50 to affix the fluid collection bag 10to a wheelchair or other objects. In one embodiment, the securementmaterial 74 is Velcro® or other hook and loop type fastening devices. Inother embodiments, the securement material for affixing, mounting,hanging or otherwise manipulating the fluid collection bag 10 onto thedesired object may include snaps, cords, buttons, or other fasteningdevices.

To use the fluid collection system 70, a user would associate themounting bracket 50 with an object, such as a bed frame, as illustratedin FIG. 3. The user would then orient the longitudinal axis LA of thefluid collection bag 10 substantially parallel to the ground andremoveably associate the fluid collection bag 10 with at least oneattachment member 62 or 66 of the mounting bracket 50. As illustrated inFIG. 3, the side openings 22 may be utilized to associate the fluidcollection bag with the attachment members 62 and 66.

Referring now to FIG. 5, a fluid collection bag 110 is illustrated. Aswith the embodiment described above in FIG. 1, the fluid collection bag110 is generally comprised of plastic. However, the fluid collection bag110 may be comprised of any impervious flexible, rigid or semi-rigidmaterial. The fluid collection bag 110 has a first side 112 and a secondside 114 along a length L₂ of the fluid collection bag 110. The fluidcollection bag 110 further includes a first end 116 and a second end 118along a height H₂ of the fluid collection bag 110. The length L₂ of thefluid collection bag 110 is generally greater than the height H₂ of thefluid collection bag 110. In one embodiment, the length L₂ of the fluidcollection bag 110 is approximately twice as long as the height H₂ ofthe fluid collection bag 110. In other embodiments, the fluid collectionbag 110 may have a length L₂ ranging from about 1.5 to about 5 times theheight H₂ of the fluid collection bag 110. However, other dimensionalproportions are contemplated and may be used in accordance with one ormore embodiments of the present invention. Despite the potentialvariation in length and height proportions, an elongated length and ashorter height assist in enabling the fluid collection bag 110 to hangon a bed frame and not contact the ground when the bed is in a lowposition. Thus, the elongated length and shorter height assist ininhibiting the potential for contamination and/or spread of infection.Such a configuration also allows for easier draining of the fluidcollection bag 110 as the fluid collection bag 110 is a farther distancefrom the floor.

While the fluid collection bag 110 is shown having a generallyrectangular shape, the fluid collection bag 110 may take other polygonaland non-polygonal forms. With any of these shapes, the fluid collectionbag 110 includes a first surface 120 and a second surface 122. In theembodiment shown in FIG. 5, the first surface 120 and the second surface122 are on opposing sides of the fluid collection bag 110 and arebounded on the peripheries by the first side 112, the second side 114,the first end 116 and the second end 118. The first surface 120 and thesecond surface 122 are generally mirror-images of each other.Furthermore, either the first surface 120 or the second surface 122 maybe positioned next to an object or support element, such as a bed frame(as shown in FIG. 7), which allows the fluid collection bag 110 to bereversible. It should be noted that while the fluid collection bag 110is typically described as being positioned next to and/or secured to abed or bed frame, in particular a medical bed or bed frame, othernon-limiting examples of various types of objects or support elementsinclude patient aids such as a pole, a chair, a wheelchair, a walker,and a person.

To aid in the reversibility of the fluid collection bag 110, the firstside 112 includes an attachment member 180 for reversibly attaching thefluid collection bag 110 to an object or support element. By“attaching,” it is meant that the attachment member 180 may be adaptedto reversibly affix, mount, hang or be manipulated to an object orsupport element. The attachment member 180 includes a pair of flexible(also referred to as “living”) hinges 181, 182, a middle portion 183separating the flexible hinges 181, 182, and a base portion 184. Theflexible hinges 181, 182 are capable of being manipulated from opposingdirections to allow the fluid collection bag 110 to be attached with thefirst surface 120 or the second surface 122 facing the object or supportelement.

The base portion 184 of the attachment member 180 may be positionedwithin a top portion of the fluid collection bag 110, as shown in FIG.5. In some embodiments, the base portion 184 is threaded through the topportion of the fluid collection bag 110 and then the top portion of thefluid collection bag 110 is sealed. In other embodiments, two pieces ofplastic film that make up the fluid collection bag 110 may be positionedaround the base portion 184 of the attachment member 180 near the topportion of the plastic films and may be sealed or welded, such as byheat or by radio frequency welding, around the base portion 184 tosecure the base portion 184 within the top portion of the fluidcollection bag 110. The sealing or welding may occur above, below and atthe sides of the base portion 184 in a manner that keeps the baseportion 184 from sliding back and forth within the top portion of thefluid collection bag 110. This is advantageous because the fluidcollection bag 110 remains properly aligned and allows for the center ofgravity of the fluid collection bag 110 to be correct. Also, if thefluid collection bag 110 were allowed to slide back and forth within thetop portion of the fluid collection bag 110, then the fluid collectionbag 110 could tilt and any readings of the volume of the fluid in thefluid collection bag 110 would not be accurate. Thus, it is advantageousto have the base portion 184 held within the top portion of the fluidcollection bag 110. Furthermore, having the base portion 184 positionedwithin the top portion of the fluid collection bag 110 allows the fluidcollection bag 110 to be positioned higher off of the floor when it isattached to an object or support element. This allows for easierdraining of the fluid collection bag 110 as the fluid collection bag 110is a farther distance from the floor.

The base portion 184 of the attachment member 180 may be linear or mayinclude angled portions, as shown in FIGS. 5 and 6. The angled portionsgenerally provide improved stability and support for the fluidcollection bag 110. In one embodiment, one end of the base portion 184includes an angled portion 185. The angled portion 185 assists inproviding support to the inlet tube 128 to maintain the position of theinlet tube 128 and to keep the inlet opening 127 from sagging orkinking. The angled portions may also allow for an increased volume offluid that can be held in the fluid collection bag 110, as the angledportions may create a greater height of the fluid collection bag 110. Insome embodiments, the angled portions may range from about 10° to about90°. Typically, the angled portions may be about 10° to about 45°. Thebase portion 184 can be, for example, a reinforcement rib or bar.Furthermore, the base portion 184 can optionally be in the form of anI-beam that extends along some or the entire length of the fluidcollection bag 110 to provide increased strength with less material.

The middle portion 183, the base portion 184 and the flexible hinges181, 182 of the attachment member 180 may be made of polyolefin, nylon,vinyl, K-Resin®, a styrene-butadiene-copolymer available from ChevronPhillips Chemical in The Woodlands, Texas as well as other types ofplastic that would provide a flexible, “living” hinge. In onenon-limiting example, a “living” hinge may be a thin strip molded into aplastic part to create a line along which the part can bend. In otherembodiments, it is contemplated that separate hangers (or hinges) madefrom other types of materials such as metal, wood, and other suitablerigid materials could be used. In yet other embodiments, it iscontemplated that some portion(s) of the attachment member 180 could bemade of one type of material, such as metal or wood, and otherportion(s) could be made of another type of material, such as plastic.Additional details regarding the flexible hinges 181, 182 is providedbelow in reference to FIGS. 8A-9 c.

The flexible hinges 181, 182 are adapted to reversibly affix, mount,hang or be manipulated to an object or support element by flexing,pulling and/or rotating the flexible hinges 181, 182 to place themaround the object or support element, such as a bed frame for example.Each of the flexible hinges 181, 182 includes a loop portion 186, 187that is adapted to be extendable and then spring back into a restingposition. The rotation and attachment capability of the flexible hinges181, 182 is described in more detail below in reference to FIGS. 8A-9C.

As noted earlier, the fluid collection bag 110 is reversible in that itcan be affixed, mounted, hung or manipulated to any side of an object orsupport element. The flexible hinges 181, 182 may be moved fromdifferent opposing directions depending on the orientation of the fluidcollection bag 110 with respect to the object or support element. Forexample, the flexible hinges 181, 182 may be flexed, pulled or rotatedtoward an object or support element and then placed around the object orsupport element to secure it thereto. Thus, the fluid collection bag 110can be used and attached to an object or support element with either thefirst surface 120 or the second surface 122 of the fluid collection bag110 facing the object or support element. This makes the attaching ofthe fluid collection bag 110 to an object or support element easier,faster and more convenient.

To describe additional details of the fluid collection bag 110illustrated in the embodiment shown in FIGS. 5 and 6, the first end 118may include an end reinforcement 124 having one or more end openings126. The end openings 126 assist in enabling the fluid collection bag 10to be handled by a nurse or other handler of the fluid collection bag110. Additionally, the end openings 126 assist in permitting the fluidcollection bag 110 to become associated with and/or affixed to othertypes of objects or support elements, such as a pole, a chair, awheelchair, a walker, and a person. The end reinforcement 124 isgenerally comprised of plastic but can be comprised of woven ornon-woven material, molded or stamped material, wood, metal, paperboard,or any rigid or flexible material, as well. The end openings 126 may begenerally elliptically-shaped, but may also take other shapes.Furthermore, the end openings 126 are of a size sufficient to facilitateaffixing, mounting, hanging or manipulating the fluid collection bag110. The end openings 126 are generally reinforced for ease of use anddurability. Although a total of three end openings 126 are depicted inthe embodiment of FIGS. 5 and 6, any number of end openings 126 suitablefor assisting in affixing, mounting, hanging or manipulating the fluidcollection bag 110 onto an object or support element may be used.

An inlet opening 127, adapted to receive an inlet tube 128, is locatedalong the first side 112 of the fluid collection bag 110. An outletopening 129, adapted to receive an outlet tube 130, is located along thesecond side 114 of the fluid collection bag 110. However, it iscontemplated that the fluid collection bag 110 may have additional inletand outlet openings and tubes. Additionally, the inlet and outletopenings 127, 129 may be located in other positions on the fluidcollection bag 110 than those illustrated in the figures. Before use ofthe fluid collection bag 110, the inlet tube 128 is associated with thefluid collection bag 110 at the inlet opening 127 at one end. Theexposed end of the inlet tube 128 is typically connected to a catheter(not illustrated). The outlet tube 130 is associated with the fluidcollection bag 110 at the outlet opening 129 at one end. The exposed endof the outlet tube 130 may be inserted into a drain tube holder 131,which is discussed in more detail below.

In the illustrated embodiment, the inlet tube 128 associates with thefluid collection bag 110 at an angle to reduce twisting and to allow forgood drainage. In one embodiment, the inlet tube 128 may associate withthe fluid collection bag 110 at an angle within the range of about 30°to about 50°. However, it is contemplated that any angle which issuitable for reducing twisting and allowing good drainage for the inlettube 128 may be used.

Near the inlet opening 127 and internal to the fluid collection bag 10is an anti-reflux mechanism 132. The anti-reflux mechanism 132 isadapted to generally surround the inlet tube 128 and comprises twosheets 132 a, 132 b having different lengths in the embodiment shown inFIG. 5. The anti-reflux mechanism 132 may be comprised of vinyl;however, other materials are contemplated for use. Some non-limitingexamples of materials for use in the anti-reflux mechanism 132 includeplastic film, molded plastic, and rubber. At one end, at least onesheet, i.e., 132 a or 132 b, of the anti-reflux mechanism 132 may beassociated with the fluid collection bag 110 at or near the inletopening 127 or the inlet tube 128 itself. The other end of theanti-reflux mechanism 132 is free. The anti-reflux mechanism 132 assistsin allowing fluid to enter the fluid collection bag 110 while inhibitingfluid from exiting the fluid collection bag 110 through the inlet tube128. To inhibit fluid from exiting through the inlet tube 128, thesheets 132 a, 132 b collapse and assist in sealing the end of the inlettube 128 internal to the fluid collection bag 110 when fluid attempts toexit through the inlet tube 128. It should be noted that other types ofanti-reflux mechanisms having different designs and/or different numbersof sheets may also be used.

A user may control the exit of fluid from the fluid collection bag 110through the outlet tube 130 using a valve 134. The valve 134 may be anyof those types of valves which are adapted to open or close a fluid pathto allow fluid to drain or keep fluid from draining. In one embodiment,the valve 134 is adapted to replace a drainage hole with a post whenactivated. In other embodiments, the valve 134 may, for example, be atwist valve, a tube that closes with a mechanical compression againstit, or a roller clamp. Additionally, in some embodiments, more than onevalve may be utilized.

As shown in FIG. 6, the outlet tube 130 may be adapted to be stored inthe drain tube holder 131. The drain tube holder 131 may be positionednear or adjacent to the first end 116 and may include a pocket, notch,opening, slit, tubing, or molded piece that easily stores the outlettube 130. Additionally, the drain tub holder 131 may be puckered or mayinclude a puckered area such that the drain tube holder 131 remains inan open position without requiring it to be manually opened by a user ofthe fluid collection bag 110. In some embodiments, the outlet tube 130may be stored while the fluid collection bag 110 is oriented with thefirst surface 120 or the second surface 122 facing the object or supportelement. For example, the outlet tube 130 may be swung from its hangingposition in FIG. 5 into the drain tube holder 131 from either directionrelative to the first surface 120 or the second surface 122. This allowsthe fluid collection bag 110 to be able to be attached to an object orsupport element with either the first surface 120 or the second surface122 of the fluid collection bag 110 facing the object or supportelement. As with the other reversible features, this makes the use ofthe fluid collection bag 110 easier and more convenient for a user. Forexample, as it is important that the inlet tube 128 face toward the headof a bed to achieve unobstructed flow, the reversibility of the fluidcollection bag 110 insures that the inlet tube 128 may always be facingin a desirable orientation. In non-reversible bags, for the inlet tube128 to face toward the head of the bed, the fluid collection bag 110must be positioned on one side or the other. This limits the ease of useand convenience of such non-reversible bags and, thus, a fluidcollection bag 110 that is reversible is particularly desirable. Thus,the reversibility of the fluid collection bag 110 is in part due to (1)the ability of the attachment member 180 to attach to an object orsupport element while the fluid collection bag 110 is oriented with thefirst surface 120 or the second surface 122 facing the object or supportelement and (2) the ability of the outlet tube 130 to be stored in thedrain tube holder 131 while the fluid collection bag 110 is orientedwith the first surface 120 or the second surface 122 facing the objector support element. This reversibility of the fluid collection bag 110has several advantages in that it offers increased ease, convenience andspeed in attaching the fluid collection bag 110 to an object or supportelement, such as a bed frame.

Additionally, the inlet tube 128 and the outlet tube 130 may include oneor more ribs 136 to discourage kinking or compression within the inletand outlet tubes 128, 130. The ribs 136 enable good flow through theinlet and outlet tubes 128, 130 and allow for good drainage of the fluidcollection bag 110. The fluid collection bag 110 may also include a vent139. The vent 139 may include a hydrophilic air vent allowing airtransfer to inhibit pressure effects such as a vacuum effect in thefluid collection bag 110. The fluid collection bag 110 may also includea printed window (not shown) on either the first surface 120, the secondsurface 122 or both the first surface 120 and the second surface 120 ofthe fluid collection bag 110. The printed window(s) may includemeasurement line(s) to enable easy urine volume output determination.

Referring now to FIG. 7, the fluid collection bag 110 is shown in use,i.e., attached to a bed frame 171, according to one embodiment of thepresent concepts. Generally, the attachment member 180 is adapted toremovably and reversibly associate with an object or support element,such as a bed frame. More specifically, the flexible hinges 181, 182 ofthe attachment member 180 are adapted to contact a bed frame 171 whereinthe flexible hinges 181, 182 are positioned around the bed frame 171.The flexible hinges 181, 182 grip the portions of the bed frame 171 andallow it to be secured thereto. The middle portion 183 may contact theside of the bed frame 171. The loop portions 186, 187 of each of theflexible hinges 181, 182 are extendable around the bed frame 171 andadapted to spring back into a resting position. The shape and flexiblenature of the flexible hinges 181, 182 enable the fluid collection bag110 to removably and reversibly attach to different types of objects andsupport elements and different desired end uses. For example, theflexible hinges 181, 182 may grip different shapes of objects, such asrounded objects, rectangular objects, L-shaped objects, etc. Inparticular, the flexible hinges 181, 182 can conform to all shapes andsizes of bed frames, wheelchairs, and other objects and supportelements. In some embodiments, the one or more end openings may also beused to assist in attaching the fluid collection bag 110 to an object orsupport element, such as a bed frame. Additionally, a cord, tape orother suitable attaching material may be used to assist in attaching thefluid collection bag 110 to the object or support element.

In FIG. 7, the inlet tube 128 is shown as extending from the inletopening 127 of the fluid collection bag 110. The angled portion 185assists in maintaining the inlet tube 128 in an optimal position forfluid flow through the inlet tube 128. The outlet tube 130 is shown asbeing stored within the drain tube holder 131. This assists inpreventing the outlet tube 130 from being contaminated. As noted above,the ability of the outlet tube 130 to be stored in the drain tube holder131 regardless of whether the first surface 120 or the second surface122 of the fluid collection bag 110 faces the object or support elementpermits use of the fluid collection bag 110 in an easier, moreconvenient and an improved manner over existing fluid collection bags.

As illustrated, the longitudinal axis LA₁ of the fluid collection bag110 is oriented substantially parallel to the ground. When a bed is in alow position, the fluid collection bag 110 does not contact the groundand the outlet tube 130 remains generally away from the ground,inhibiting the potential for contamination and/or spread of infection.As the outlet tube 130 is positioned in the tube holder 131 as shown inFIG. 6, this also prevents or inhibits the potential for contaminationand/or spread of infection.

As mentioned above, the end openings 126 on the end reinforcement 124are provided to enable attachment of the fluid collection bag 110 toobjects or support elements in addition to beds. Such additional objectsor support elements include, but are not limited to, patient aids suchas a pole, a chair, a wheelchair, a walker, and person. In someembodiments, other methods of affixing, mounting, hanging or otherwisemanipulating the fluid collection bag 110 onto the desired object orsupport element may include the use of securement materials such astape, Velcro® or other hook and loop type fastening devices. In otherembodiments, the securement material for affixing, mounting, hanging orotherwise manipulating the fluid collection bag 110 onto the desiredobject or support element may include snaps, cords, buttons, or otherfastening devices.

To use the fluid collection bag 110, a user would associate theattachment member 180, particularly the flexible hinges 181, 182, to anobject or support element, such as a bed frame, as illustrated in FIG.7. The user would then orient the longitudinal axis LA₁ of the fluidcollection bag 110 substantially parallel to the ground and removablyand reversibly associate the fluid collection bag 110 with the object orsupport element, such as a bed frame 171. Although FIG. 7 illustrates anexample in which the end openings 126 are not utilized to attach thefluid collection bag 110 to an object or support element, otherembodiments are contemplated wherein the end openings 126 assist inattaching the fluid collection bag 110 to an object or support element.

Referring to FIGS. 8A-8C, a fluid collection bag 210 includes a firstsurface 220, a second surface 222, an inlet tube 228, an outlet tube230, and an attachment member 280. In general, the fluid collection bag210 is similar (but not necessarily identical) to the fluid collectionbag 110 described above. The attachment member 280 has a middle portion283 that is coupled to a pair of loop portions 286, 287 for attaching toa bed frame 271 or other objects or support elements.

The loop portions 286, 287 are rotatable around the middle portion 283for reversibly attaching the fluid collection bag 210 to either side ofthe bed frame 271. For example, in a first attachment position(illustrated in FIG. 8A) the loop portions 286, 287 are orientedperpendicular to the middle portion 283 and away from the first surface220. In the first attachment position the first surface 220 ispositioned to face away from the bed frame 271, while the second surface222 is positioned to face toward the bed frame 271.

To reverse the fluid collection bag 210, the loop portions 286, 287 arerotated 180°, through one or more intermediate positions (e.g., FIG.8B), until reaching a second attachment position (illustrated in FIG.8C). The exemplary intermediate position illustrated in FIG. 8B has theloop portions 286, 287 rotated about 90° relative to the firstattachment position, the loop portions 286, 287 being generally parallelto the middle portion 283. In the second attachment position, the secondsurface 222 is positioned to face away from the bed frame 271 and thefirst surface 220 is positioned to face toward the bed frame 271.

When reversing the fluid collection bag 210, the outlet tube 230 is alsoreversed from the first surface 220 to the second surface 222. Thereversal of the outlet tube 230 is described in more detail below inreference to FIGS. 10A-10E.

Referring to FIGS. 9A-9C, the attachment member 280 is shown moreclearly to illustrate a pair of living hinges 281, 282 for coupling theloop portions 286, 287 to the middle portion 283. Optionally, theattachment member 280 can be a single unitary molded component.Furthermore, the living hinges 281, 282 are attached to the middleportion 283 via a pair of flexible portions 290, 291. When theattachment member 280 is in the first attachment position (illustratedin FIG. 9A), the flexible portions 290, 291 are generally compressedbetween the living hinges 281, 282 and the middle portion 283. When theattachment member 280 is in the intermediate position (illustrated inFIG. 9B), the flexible portions 290, 291 are partially stretched toallow the rotational movement of the loop portions 286, 287. When theattachment member 280 is in the second attachment position (illustratedin FIG. 9C), the flexible portions 280, 291 are generally fullystretched to allow the 180° position reversal of the loop portions 286,287. The flexible portions 290, 291 can be thinned portions to permiteasy bendability with respect to the middle portion 283.

Referring to FIGS. 10A-10E, the outlet tube 230 is also reversed whenreversing attachment of the fluid collection bag 210 from one side ofthe bed frame 271 to another side of the bed frame 271. Reversal of theoutlet tube 230 provides easy access to a user, regardless of which oneof the first and second surfaces 220, 222 is facing toward the bed frame271.

In the first attachment position (illustrated in FIGS. 10A-10B), theoutlet tube 230 is inserted inside a first drain tube holder 231 a,which is located on the first surface 220 of the fluid collection bag210. In this position, a valve 234 is located adjacent to the firstdrain tube holder 231 a.

When reversing the fluid collection bag 210, the outlet tube 230 isremoved from the first drain tube holder 231 a and is rotated through aplurality of intermediate positions. For example, the outlet tube 230 isrotated about 90° downward in an exemplary intermediate position(illustrated in FIG. 10C). In this intermediate position, the outlettube 230 reaches its maximum extension away from the fluid collectionbag 210. To complete the reversibility of the outlet tube 230, theoutlet tube is rotated to the second attachment position (illustrated inFIGS. 10D-10E) in which the outlet tube 230 is inserted in a seconddrain tube holder 231 b, which is located on the second surface 222 ofthe fluid collection bag 210.
